[0002] In the past, a handle mechanism for opening and closing a cabin door of an aircraft is known, which includes an inner handle, an outer handle and a connecting structure between the inner handle and the outer handle. The inner handle rotates to drive a raised portion 104 at a corresponding position of a cam portion 34 in the connecting structure to escape from a triangular recess 90 of a cylindrical cover 32 engaged therewith, and at the same time, a raised portion 106 on the other end side of the cam portion 34 escapes from a triangular recess 96 of an outer handle 26 engaged therewith, so as to pop out the outer handle and drive the outer handle to rotate together, thereby opening the cabin door.

[0003] As described above, the above-mentioned handle mechanism can only make the outer handle pop out of the handle slot from the inside of the cabin door, and cannot make the outer handle pop out of the handle slot from the outside of the cabin door. Therefore, the cabin door can only be opened from the inside of the cabin door by the inner handle, and cannot be opened from the outside of the cabin door by the outer handle.

[0004] Moreover, in the above-mentioned handle mechanism, when the hatch door is opened from the inside of the hatch door by the inner handle, the inner handle will drive the outer handle to rotate together and cannot rotate independently, so the opening action will become more strenuous. Summary of the invention

[0007] According to the above structure, by making the slider slide in the first connecting hole, the positioning hole and the second connecting hole, the inner handle can be separated or connected from the outer handle, so that the inner handle can be rotated alone inside the cabin door, and the outer handle can be rotated outside the cabin door to drive the inner handle.

[0008] The handle mechanism of the second aspect of the present invention is based on the handle mechanism of the first aspect of the present invention, and the outer handle pop-up structure includes: a sleeve portion, which is nested in the outer peripheral side of the outer handle and the inner peripheral side of the handle rocker arm from one side of the axial direction, and is composed of a tube bottom and a tube wall portion, the tube bottom is fixed to the handle rocker arm, and the tube wall portion is between the outer handle and the handle rocker arm; an outer handle spring, which connects the tube bottom of the sleeve portion with the outer handle; an outer handle pressing portion, which is nested in the outer handle in a manner of pressing the outer handle from the other side of the axial direction, and is formed with a first driving portion that can drive the sliding connection from the other side of the axial direction; and an outer handle pressing spring, which connects the outer handle to the outer handle pressing portion, and when the sliding connection moves to the first position, in the positioning hole, the first driving portion abuts against the sliding connection from the other side of the axial direction.

[0009] According to the above structure, by forming an outer handle pop-up structure composed of a sleeve portion, an outer handle spring, an outer handle pressing portion and an outer handle pressing spring, when the sliding connection moves to the first position, not only can the inner handle be separated from the outer handle, but the first driving portion can also abut against the sliding connection from the other side of the axial direction to fix the sliding connection in the axial direction, thereby locking the outer handle in the first position through the sliding connection.

[0010] The handle mechanism of the third aspect of the present invention is based on the handle mechanism of the second aspect of the present invention, and the first drive part is formed as an inclined surface inclined relative to the axial direction, and the inclined surface extends to the sleeve part in the radial direction and can reciprocate along the axial direction in the first drive hole.

[0011] According to the above structure, by forming the first driving portion into an inclined surface inclined relative to the axial direction, and the inclined surface extends radially to the sleeve portion and can reciprocate axially in the first driving hole, it can be ensured that when the first driving portion moves from the other side of the axial direction, its inclined surface can abut against the slider and drive the slider to move radially outward.

[0012] The handle mechanism of the fourth aspect of the present invention is based on the handle mechanism of the third aspect of the present invention, and when the outer handle is located at the second position, the sliding connection member is pressed against the outer peripheral surface of the outer handle.

[0013] According to the above structure, when the outer handle is in the second position, the sliding connection is crimped against the outer peripheral surface of the outer handle. On the basis of fixing the axial position of the outer handle by the connecting structure, the axial fixation of the outer handle can be further ensured by crimping the sliding connection against the outer peripheral surface of the outer handle.

[0014] The handle mechanism of the fifth aspect of the present invention is based on the handle mechanism of the fourth aspect of the present invention, and also includes a second driving part. The second driving part is arranged on the radial outside of the sliding connection member, and is composed of a steel ball in contact with the sliding connection member and a sliding spring in contact with the steel ball, and always applies force to the sliding connection member radially inward.

[0015] According to the above structure, by providing the second driving part on the radially outer side of the sliding connection member, and by configuring the second driving part to be composed of a steel ball and a sliding spring, the sliding connection member can be always urged radially inward by a simple structure.

[0016] The handle mechanism of the sixth aspect of the present invention is based on the handle mechanism of the first aspect of the present invention, the first position is the position where the outer surface of the outer handle is flush with the outer surface of the handle box, and the second position is the position where the outer surface of the outer handle pops out from the outer surface of the handle box.

[0017] According to the above structure, by setting the first position to a position where the outer surface of the outer handle is flush with the outer surface of the handle box and setting the second position to a position where the outer surface of the outer handle pops out from the outer surface of the handle box, the outer handle can be maintained in the first position when the inner handle is separated from the outer handle, and the outer handle can be maintained in the second position when the inner handle is connected to the outer handle.

[0081] In the handle mechanism 100 of the present invention, the cylindrical inner handle body 12 of the inner handle 1 and the cylindrical outer handle body 21 of the outer handle 2 are coaxially arranged. Therefore, in the following description, for the convenience of description, Figure 1 As shown, the direction of the central axis of the inner handle 1 and the outer handle 2 is set to the Z direction, one side thereof is set to the Z1 side, and the other side is set to the Z2 side, and a direction perpendicular to the direction of the central axis is set to the X direction, one side thereof is set to the X1 side, and the other side is set to the X2 side.

[0082] (First Embodiment)

[0083] (Overall Structure of Handle Mechanism 100)

[0084] Figure 1 is a schematic diagram showing the general components of the handle mechanism. Figure 2 (A) is a schematic diagram showing the handle mechanism of the first embodiment in a state where the outer surface of the outer handle is flush with the outer surface of the handle box, Figure 2 (B) shows the use of plane AA to Figure 2 A cross-sectional view of the handle mechanism shown in (A). Figure 1 , Figure 2 (A) and Figure 2 As shown in (B), the handle mechanism 100 includes: an inner handle 1, wherein the inner handle 1 includes a cylindrical inner handle body 12 and a gripping portion 11 extending from the inner handle body 12 to the outer peripheral side; an outer handle 2, wherein the outer handle 2 includes a cylindrical outer handle body 21, wherein the outer handle body 21 is embedded in the handle box 5 in a manner that it can move relative to the handle box 5; and a connecting structure 3, wherein the connecting structure 3 can connect or separate the inner handle 1 and the outer handle 2; an outer handle pop-up structure 4, wherein the outer handle pop-up structure 4 can eject the outer handle 2 from the outer surface (i.e., Figure 3 Z2 side surface in the middle) pops up; and a handle bracket 6, the handle bracket 6 includes a cylindrical bracket body 61 mounted on the outer peripheral side of the handle rocker arm 31 and a bracket edge 62 extending radially outward from the bracket body 61, and the bracket edge 62 is fixed to the cabin door (omitted from the figure).

[0085] like Figure 2 and Figure 3 As shown, the inner handle body 12 of the inner handle 1 is coaxially arranged with the outer handle body 21 of the outer handle 2. Specifically, the inner handle body 12 is roughly cap-shaped, including a bottom wall portion 121 and a peripheral wall portion 122. The outer peripheral end of the bottom wall portion 121 is embedded in the step portion 312 of the inner peripheral surface of the end portion on the Z1 side of the handle rocker arm 31. The inner handle 1 and the outer handle 2 are fixed as a whole via a bolt member (omitted from the figure). Both can rotate relative to the handle box 5, and the Z2 side end surface ( Figure 2 , 3 The lower end surface in the middle) is rotatably connected to the Z1 side end surface ( Figure 2 , 3 The upper end surface of the contact).

[0086] In this embodiment, in order to ensure the airtightness between the inner handle 1 and the outer handle 2, as shown in FIG. Figure 2As shown, the connection between the inner handle body 12, the handle rocker arm 31 and the handle box 5 is airtight. Specifically, the connection between the inner handle 1 and the step portion 312 of the handle rocker arm 31 and the connection between the Z2 side end surface of the handle rocker arm 31 and the Z1 side end surface of the handle box 5 are both airtight. In this way, the airtightness of the storage space surrounded by the inner handle body 12, the handle rocker arm 31 and the handle box 5 can be ensured.

[0087] like Figure 2 and Figure 3 As shown, the outer handle pop-up structure 4 capable of popping out the outer handle 2 is accommodated in the above-mentioned space. The outer handle pop-up structure 4 includes: a sleeve portion 45, the sleeve portion 45 is formed to include a sleeve bottom 451 and a sleeve wall portion 452 extending from the sleeve bottom 451 to the Z2 side, the sleeve bottom 451 protrudes radially outward relative to the outer peripheral surface of the sleeve wall portion 452, and the protruding portion is engaged with the step portion 312 (such as Figure 2 ), that is, the end on the Z1 side is embedded in the step portion 312 of the handle rocker arm 31; an outer handle spring 44, one end of the outer handle spring 44 on the Z1 side is connected to the inner circumferential surface of the tube bottom 451 of the sleeve portion 45, and one end on the Z2 side is connected to the end surface on the Z1 side of the outer handle body 21 of the outer handle 2 to elastically support the outer handle 2; an outer handle pressing portion 42, the outer handle pressing portion 42 is arranged inside the outer handle 2, including an outer handle button 421 nested inside the outer handle 2 and an outer handle pressing block 422 that is formed as a whole with the outer handle button 421 and is trapezoidal in the XZ plane; and an outer handle pressing spring 43, the outer handle pressing spring 43 is arranged in the outer handle 2 and clamped between the outer handle 2 and the outer handle pressing portion 42, one end of the outer handle spring 43 on the Z1 side is connected to the tube bottom surface on the Z1 side of the outer handle body 21 of the outer handle 2, and one end on the Z2 side is connected to the outer handle pressing portion 42.

[0088] In this embodiment, both the outer handle spring 44 and the outer handle pressing spring 43 are compression coil springs.

[0089] In the above-mentioned outer handle pop-up structure 4, as Figure 3 As shown, a long hole 4521 extending along the axial direction Z is formed in the cylindrical wall portion 452 of the sleeve portion 45, and a circular hole 212 is formed in the outer handle body 21 of the outer handle 2, and the circular hole 212 and the long hole 4521 always overlap in the axial direction Z. An outer handle pin 46 is inserted through the long hole 4521 and the circular hole 212, and the outer handle pin 46 is moved within the axial range of the long hole 4521 to slide and connect the outer handle 2 to the sleeve portion 45.

[0090] Furthermore, when the outer handle 2 is moved to Figure 2In the first position shown in FIG. 1 , the outer handle pin 46 slides in the long hole 4521 until it abuts against the inner edge of the hole on the Z1 side of the long hole 4521. Figure 3 In the second position shown, the outer handle pin 46 slides in the long hole 4521 until it abuts against the inner edge of the hole on the Z2 side of the long hole 4521. In this way, the movement range of the outer handle 2 in the axial direction Z relative to the sleeve portion 45 can be limited by the long hole 4521 formed in the sleeve portion 45, the circular hole 212 formed in the outer handle body 21 of the outer handle 2, and the outer handle pin 46 inserted through the long hole 4521 formed in the sleeve portion 45, and the circular hole 212 formed in the outer handle body 21 of the outer handle 2.

[0091] Moreover, if Figure 4 As shown, a substantially T-shaped positioning hole 4522 is formed in the wall portion 452 of the sleeve portion 45. The positioning hole 4522 is included in Figure 2 At the first position shown, a sliding connection hole 4522A is clamped between the second connection hole 211 of the outer handle body 21 of the outer handle 2 and the first connection hole 311 of the handle rocker arm 31 in the X direction, so that the slider 32 can reciprocate in the X direction, and a first drive hole 4522B extends from the sliding connection hole 4522A to the Z2 side and allows the outer handle press block 422 to reciprocate in the axial direction Z.

[0092] In addition, in the above-mentioned outer handle pop-up structure 4, the outer handle presses the stopper 422 as shown in FIG. Figure 2 , 3 As shown, it is fixed to the outer handle button 421, and its trapezoidal cross-section in the XZ plane includes an upper bottom surface 4221, a lower bottom surface 4222 and two inclined surfaces 4223. The inclined surfaces 4223 are inclined relative to the Z direction and extend to the barrel wall portion 452 of the sleeve portion 45 in the X direction, and are aligned with the first drive hole 4522B of the positioning hole 4522 of the barrel wall portion 452 in the Z direction.

[0093] In addition, as the connection structure 3, in this embodiment, Figure 2 The handle rocker arm 31 is shown as comprising a handle rocker arm 31, wherein the handle rocker arm 31 is formed with a first connecting hole 311 extending in the radial direction X, wherein a compression spring 34 is received in the first connecting hole 311, wherein one radial inner end of the compression spring 34 is connected to the slider 32 (i.e., the sliding connecting member) via a steel ball 33, and one radial outer end is sealed airtightly by a sealing cover 35; a sliding connecting hole 4522B (refer to Figure 4 ); and when the outer handle 2 is in Figure 2In the first position shown, a second connection hole 211 is formed at a portion of the outer handle body 21 corresponding to the sliding connection hole 4522A. The first connection hole 311, the sliding connection hole 4522A and the second connection hole 211 are continuous from the radial outside to the radial inside, allowing the slider 32 to reciprocate therein.

[0094] By setting the connection structure 3 as described above, when the outer handle 2 slides to Figure 2 In the first position shown, the slider 32 slides radially inward from the first connection hole 311 of the handle rocker arm 31 until it completely slides out of the first connection hole 311, and the outer handle 2 is separated from the inner handle 1. In this way, when the operator rotates the inner handle 1 from inside the cabin door to rotate it together with the handle rocker arm 31, the synchronous rotation of the inner handle 1 and the handle rocker arm 31 will not be transmitted to the outer handle 2, so the inner handle 1 can be operated alone from inside the cabin door.

[0095] In addition, when the operator presses the outer handle button 421 of the outer handle pressing portion 42 from outside the hatch and releases it, the outer handle 2 pops out from the handle box 5 and moves to the Figure 3 In the second position shown, first, the outer handle pressing block 422 of the outer handle pressing portion 42 enters the first driving hole 4522B of the positioning hole 4522 of the barrel wall portion 452 of the sleeve portion 45 from the Z1 side, and continues to slide in the first driving hole 4522B until it abuts against the slider 32, and pushes the slider 32 to move radially outward, and completely slides out of the second connecting hole 211 and enters the sliding connecting hole 4522A and the first connecting hole 311. Then, after the outer handle pressing portion 42 is released, under the action of the restoring force of the outer handle spring 44 of the outer handle pop-up structure 4, the outer handle 2 moves to the Z2 side, and at the same time, the slider 32 stops moving radially outward and turns to move radially inward, and the inner circumference of the slider 32 is pressed against the outer circumference of the outer handle 2. At this time, the outer handle 1 is connected to the inner handle 1 via the connecting structure 3. When the operator rotates the outer handle 2 from outside the cabin door, the rotation of the outer handle 2 can drive the inner handle 1 to rotate synchronously via the connecting structure 3.

[0096] In addition, the connection structure 3 combined with the outer handle pop-up structure 4 has the function of connecting the inner handle 1 with the outer handle 2, and also has the function of locking the outer handle 2 on its outer surface 22 (i.e. Figure 2 The surface on the Z2 side shown in FIG. 1 is connected to the outer surface 51 of the handle box 5 (i.e. Figure 2 The first position where the surface of the Z2 side is flush with the outer surface 22 (i.e. Figure 3 The surface on the Z2 side shown in the figure acts as a second position that pops out from the outer surface 51 of the handle box 5.

[0097] Specifically, if Figure 2As shown, when the slider 32 moves to the first position, the portion of the slider 32 located at the sliding connection hole 4522A of the positioning hole 4522 is fixed in the axial direction Z, and the portion of the slider 32 located at the second connection hole 211 is also fixed in the axial direction. At this time, the outer handle 2 is fixed at a position where its outer surface 22 is flush with the outer surface 51 of the handle box 5.

[0098] like Figure 3 As shown, when the slider 32 moves to the second position, the portion of the slider 32 located at the positioning hole 4522 and the first connecting hole 311 is fixed in the axial direction Z, and the remaining portion of the slider 32 is pressed against the outer peripheral surface of the outer handle 2 under the action of the restoring force of the compression spring 34. At this time, the outer handle 2 is fixed in the axial direction Z via the outer handle pop-up structure 4 and the pressing of the slider 32 and the outer handle 2. In this way, the outer handle 2 can be fixed at a position where its outer surface 22 pops out from the outer surface 51 of the handle box 5.

[0099] (Technical Effects of the Present Embodiment)

[0100] According to the handle mechanism 100 constructed as described above, when the outer handle 2 is stored in the handle box 5, the inner handle 1 can be separated from the outer handle 2 so that the operator can rotate the inner handle 1 alone from inside the cabin door, and when the outer handle 2 pops out from the handle box 5, the inner handle 1 can be connected to the outer handle 2 so that the operator can rotate the outer handle 2 from outside the cabin door.

[0101] Furthermore, when the outer handle 2 is stored in the handle box 5 , the outer handle 2 can be fixed at a flush position stored in the handle box 5 , and when the outer handle 2 pops out from the handle box 5 , the outer handle 2 can be fixed at the pop-up position.

[0102] (Modification of the first embodiment)

[0103] In the first embodiment, the structure of the handle mechanism 100 including the inner handle 1, the outer handle 2, the connecting structure 3 and the outer handle pop-up structure 4 and the technical effects thereof are described in detail.

[0104] In this variation, except that the matching structure between the outer handle pressing block of the outer handle pressing portion and the inner circumferential surface of the outer handle is different from that of the first embodiment, the arrangement of the remaining parts is the same as that of the first embodiment.

[0105] Specifically, if Figure 5As shown, the dimension of the inclined surface 4223A of the outer handle pressing block 422A in the axial direction Z is larger than the dimension of the inclined surface 4223 of the outer handle pressing block 422 of the first embodiment in the axial direction Z. When the slider 32 moves to a position where the outer surface 22 of the outer handle 2 is flush with the outer surface 51 of the handle box 5, a portion of the inclined surface 4223A of the outer handle pressing block 422A on the Z1 side abuts against the inclined guide portion 213A formed on the inner peripheral surface of the outer handle body 21A of the outer handle 2A, and at the same time, a portion of the inclined surface 4223A on the Z2 side abuts against the inner peripheral surface of the slider 32. In this way, compared with the above-mentioned first embodiment, the outer handle 2 can be more reliably guided to the first position.

[0106] According to this variation, in addition to achieving the same effect as the first embodiment in that the inner handle can be rotated alone from inside the cabin door and the outer handle can be rotated from outside the cabin door to drive the inner handle to rotate synchronously, the outer handle 2 can be guided to the first position more reliably.

[0107] The various embodiments of the present invention and their variations have been described in detail above. However, in addition to the technical solutions described in the above-mentioned embodiments and their variations, the elements of the above-mentioned embodiments and their variations can be combined to obtain the technical solutions of the present invention without violating the purpose of the present invention.

[0108] In the above-described embodiment and its modified example, a slider is used as the sliding connection member, but the present invention is not limited thereto, and other shapes may be used.

[0109] In the above-mentioned embodiment and its modified example, a compression coil spring is used in the outer handle pop-up structure to drive the outer handle to reciprocate in the axial direction, but the present invention is not limited to this. Other driving components such as a cylinder can also be used to drive the outer handle to reciprocate in the axial direction.

[0110] In the above-mentioned embodiment and its modified example, the positioning hole of the sleeve portion is formed into a roughly T-shape, but the present invention is not limited to this. As long as it includes a sliding connection hole for the sliding connection part to enter and exit and a first drive hole for the outer handle pressing block of the outer handle pressing portion to enter and exit, it can also be formed into other shapes.

[0111] In the above-mentioned embodiment and its modified example, as the first driving part for driving the sliding connection member, a sliding spring is connected to the sliding connection member via a steel ball, but the present invention is not limited thereto, and other settings may also be adopted.

[0112] In the above-mentioned embodiment and its modified examples, a long hole formed in the sleeve portion, a round hole formed in the outer handle and an outer handle pin inserted through the long hole and the round hole are used to limit the axial movement range of the outer handle relative to the sleeve portion, but the present invention is not limited to this and other methods may also be used.

[0113] In the above-mentioned embodiments and their variations, the inner handle and the outer handle are fixed together by bolts, but the present invention is not limited thereto, and other fixing methods may also be used.

[0114] In the above-mentioned embodiment and its modified example, as the second driving part for driving the sliding connection, the shape of the outer handle pressing block in the XZ plane is set to a trapezoid, but the present invention is not limited to this. As long as it extends radially to the sleeve part, it can also be set to other shapes such as a rectangle.
